SCRUBBlNG-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 778,427, dated December27, 1904. Application filed February 27, 1904. Serial No. 195,647.

T0 00% whom it may concern:

Be it known that I, HENRY J OHN NoLL, a citizen of the United States,and a resident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements inScrubbing-Machines; and I do hereby declare that the following is afull, clear, and exact description thereof.

My invention has for its object to provide simple, economical, andeflicient scrubbingmachines each comprising a rotary-drive fountain-fedbrush. 1

Hence said invention consistsin certain peculiarities of constructionand combination of parts hereinafter particularly set forth withreference to the accompanying drawings and subsequently claimed.

Figure 1 of the drawings represents a verdicates a box-like frame havinga removable cover B, provided with a valance b, and a removable pan 0 issupported on lugs 0 inside the frame immediately under its cover. The

casing.

Arranged to turn in the bracket G and par titions H parallel to sides ofthe frame is a horizontal shaft I in miter-gear with a vertical centershaft J, for which said bracket is also provided with abearing.Supported on the shaft J to turn therewith under the outlet-pipe D ofthe pan 0 is a circular basin K,

having outlet-pipes L, thatextend down through the head of a circularbrush M in loose central engagement with said shaft. The

brush-head normally rests upon a lower arrnular flange e ofthe shaft J,and a spiral spring N surrounds said shaft under tension between saidbrush-head and the basin aforesaid, the brush being rotary with itsshaft within the space bounded by the ends and partitions of the frameaforesaid.

Fast on the ends of the shaft I are spurwheels P, in mesh with similarwheels Q, on spindles R, that have their bearings in the sides andpartitions of the machine-frame. Traction-wheels S are also fast on thespindles R, and rubber tires 3 are preferably employed on said wheels.

The sides of the machine-frame are provided with outer studs 9, and ahandleT is connected to albail U, that is loose at its ends on saidstuds.

The maclnne being pushed over a surface on its'wheels S, rotary motionis imparted to the brush M, that also bears on said surface underpressure of the spring N, and said machine being reversed there is readyyield of said brush in anupward direction to permit 'a shift ofdirection in the bend of its tufts.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

v A scrubbing-machine comprising a suitable frame mounted on wheels andprovided with a handle, a horizontal shaft within the frame.

in gear-train with the wheels, a vertical shaft in gear with the shaftaforesaid, a brush rotative with the vertical shaft but movablelongitudinally of the same, a pan supported'in said frame, acock-controlled pipe depending g i i .ii

from the pan, a basin in connection with said the county of Milwaukeeand State of \Visvertical shaft under the pipe aforesaid, pipes eonsin,in the presence of two witnesses. leading from the basin through thehead of i 1 T s T T T r the brush, and a spring arranged between saidH13} 1x1 JOUA BOLL' 5 basin and brush. Witnesses:

In testimony that I claim the foregoing I N. E. OLIPHANT, have hereuntoset my hand, at Milwaukee, in R. J. BARsoH'.
